Not Seeing Results: Anyone here took a while to see benefits?

Any late-bloomers out there? If you didn’t see any benefits with initial training ( by “initial” i mean completing a full 19 day program, at least), but stuck with it and eventually saw some?

Training not working for me thus far. I finished the 19 sessions, took a five day break, and just did another sessions. I was training in a single -n mode, and also doing practice exercises in dual-mode in the final five days (levels 1 and 2 only as not to go against recommendation). I did not notice any improvement in my daily life in terms of memory, concentration, or processing speed. I reached N4.7 (3rd level) at the end of my 19 days. My N went up slightly to 4.9 today, but even that is not very impressive since I had higher averages at 2 previous sessions. Furthermore, I took a makeshift iq test ( I used the logical reasoning section from an LSAT book. In my opinion, it’s a much more reliable test of fluid intelligence than the internet iq tests, and has more real-life correlation than plugging through a bunch of visual patterns) and scored the same as I did a few years ago.

It would be encouraging to see if others have been in this situation. I feel like I might just end up quitting if I continue not seeing results

I want to give it one more shot and plan to train for 19 more days in dual-mode. I will even try to do two sessions a day. If that doesn’t work, than that’s that.
